"What do we do, Master?" June asked. "We can't fly any more to New Alexandria this way. The galewing form is not big enough to carry everyone."
"I know…"
"What are you talking about?" Mira asked.
"June can shapeshift like all the clones, as you know... We wanted to fly to New Alexandria."
"And I guess we can't do it anymore, right? Doesn't June have something to carry us all?"
"Just the form of a black wyvern, but that would be a stupid move."
Erik saw the shocked looks on the faces of Mira, Emily, and Amber at the mention of a black wyvern. He understood why they had it.
They learned from the other clones that, in order for them to be able to shapeshift, they had to drink the creature's blood.
That meant that Erik must either have killed one or found a dead one.
